Rediff educates me saying that Wives observe a 24-hour long fast for the long life and wellbeing of their husbands.
Once the moon-worshipping is done, the wives look at the moon through a sieve and then immediately turn to look at their husbands -- it is said that a woman should look at no-one but her husband straight after she has seen the moon through the sieve.
After the moon-worshipping, women receive their first bite of food from their husbands. The fast begins the night before in the presence of both the moon and the husband and ends only after the woman sees her husband and the moon together the following evening.
Oh..so touching!!...Wonder whats the equivalent fast for the husbands?
